The US state of Florida, scene of America’s latest school shooting, on Wednesday passed bill that raises the minimum age to buy firearms to 21 while funding a program that allows some teachers and school employees to be armed.

The “Marjory Stoneman Douglas High School Public Safety Act,” which takes its name from last month’s mass shooting in which 17 people including 14 students were killed, passed the legislature’s lower house a day after clearing the senate.

It will now be sent to Governor Rick Scott to sign.

The Republican has not indicated whether he would veto the law, but he has previously expressed opposition to US President Donald Trump’s call to arm teachers.

America’s long moribund gun control debate was revived by survivors of the Parkland shooting, who a day after their school was attacked launched the “Never Again” movement demanding legislative action.

The bill raises the minimum age to purchase all firearms from 18 to 21 – a move opposed by the powerful National Rifle Association lobby group – bans modification devices that make a semi-automatic weapon fully automatic, and increases mental health funding.

It also includes a voluntary “guardian program” named after Coach Aaron Feis who was slain in the Parkland attack, which is intended to “aid in the prevention or abatement of active assailant incidents on school premises” by allowing some school employees to be armed.

The program is mainly aimed at staff such as coaches and school personnel, with teachers eligible if they have military or law enforcement experience.

Bringing more guns into school has been a controversial idea, but lawmakers defended the bill.

‘Poison pill’

“I understand the angst about the guardian program but I can’t help but think about the coaches who literally ran in as shields to protect their students ... while guys with guns were standing outside,” said Republican member Chris Latvala.

“If there are school personnel that want to go to the training to help shield the students and protect them, they should have the opportunity,” he continued.

Meanwhile, Democrat legislators said the guardian program was a “poison pill” in a law otherwise taking necessary steps towards gun control.

“I’m taking and swallowing that poison pill.
As much as I don’t want to, I can’t look in the mirror and leave here and think ‘I did nothing to help’,” said Representative Joseph Geller.

African-American representatives also expressed fears that arming black school employees could leave them vulnerable to being mistaken for attackers by police arriving on the scene of a mass shooting.

Florida has seen three mass shootings in under two years – 49 were killed at an Orlando nightclub in 2016, five at Fort Lauderdale’s international airport in 2017, and now 17 in Parkland.

The bill does not ban the sale of the AR-15 assault rifle – the weapon used by Nikolas Cruz – one of activists’ key demands.

Meanwhile, parents of American children killed in gun violence implored Congress to seize the moment and enact far-reaching gun reform, as the momentum for taking action stalls in politically divided Washington.

With no lawmakers from the controlling Republican Party present, a group of Senate Democrats held a makeshift hearing in the US Capitol to hear testimony from grieving relatives, a survivor of the Parkland shooting, teachers and police officers demanding change to the nation’s laws.

“How many more children are going to need to be slaughtered?” 17-year-old David Hogg asked the senators.
